Klinefelter Syndrome Mosaicism 46,XX/47,XXY: A New Case and Literature Review.
Article in Journal of pediatric genetics, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Most cases of Klinefelter syndrome (KS) have 47,XXY karyotype. We reported the first case of 46,XX/47,XXY KS whose genital ambiguity was detected prenatally with postnatal confirmation of the mosaicism and ovotesticular disorder of sex development (OT-DSD). The paternal origin of the extra X chromosome was identified using trio cytogenomic single-nucleotide polymorphism array. Additional 18 cases were also reviewed. The clinical presentation of 46,XX/47,XXY is age-dependent with two age peaks, including ambiguous genitalia during infancy and gynecomastia with or without cyclical hematuria and left scrotal pain and mass in adolescence. The 46,XX is the predominant karyotype both in peripheral blood and gonadal tissue. The risk of germ cell tumor is very high throughout life in these individuals. Individuals with 46,XX/47,XXY mosaicism should be treated more as OT-DSD other than a simple mosaic KS. A multidisciplinary approach and long-term monitoring are necessary.
